DEVICE FOR DRYING EXHAUST-STEAM.

SPECIFICATION forming part of Letters Patent No. 653,334, dated July 10,1900'.

Application filed October 19, 1899. Serial No. 734,118. (No model.)

To all whom it may concern:

Be it known that I, LEON F. N. BALDWIN, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements in Devices forDrying Exhaust-Steam, of which the following is a specification,reference being had therein to the accompanying drawings.

Like letters indicate like parts.

Figure 1 is a view of my invention as seen on line ,2 z of Fig. 2. Fig.2 is a View of the same as seen on line a: a: of Fig. 1.

My invention is an apparatus for drying the exhaust-steam from the portsof the cylinder of a steam-engine, and is especially adapted for use inautomobile vehicles operated by steam.

My invention consists of thecombination of a steam-boiler having hot-airfiues through it, a chamber above the boiler into which said fiues open,a vertical smoke-pipe discharging at both ends and connected with saidchamber, a steam-exhaust pipe opening into said chamber, and aperforated plate extending through said chamber, with a tongueprojecting into the smoke-pipe, which plate is provided with a series ofangularly-inclined baffler-plates extending over the perforations of theplate, as hereinafter particularly described.

In the drawings, A represents a steam-boiler, through which pass thehot-air fines a a. These flues open through the top plate I). On the topof the boiler A is the chamber B. A steampipe 0 enters said chamber.

D is avertical smoke-pipe open at both ends and connected with thechamber B by a pipe E. A plate F is fastened to the sides of the chamberB and extends nearly horizontal, but somewhat inclined, over the topplate I) of the boiler and a short distance therefrom. This plate F hasa tongue G extending on one side, which is curved at its end and extendsthrough the pipe E and into the smoke-pipe D. The plate F has a seriesof perforations c 0, arranged in parallel rows, and over the rows ofperforations respectively, are angularly-inclined ba'l'lier; plates 11,parallel with each other and flaring upwardly toward that end of thechamber B where the pipe 0 opens therefrom. The plates H are fastened tothe plate ;F by the bolts cl d.

A damper I extends across the smoke-pipe D near its top and is pivotallyhung, as shown at e in Fig. 1, through a slot on the side of said pipe.The damper I has an arm m extending outside of the pipe D, and on theend of the arm' is an adjustable Weight n.

The heat, gas, and smoke pass up through the fines aof the steam-boilerA into the chamber B and also through the perforations c c of the plateF and are deflected by the baffierplates H toward the pipe E and arecarried by the pipe E into the pipe 'D, whence they are discharged intothe outer air. The pipe 0 conducts exhaust-steam from the ports of thecylinder of the steam-engine into the chamber B. The plates F and H areheated by the hot air which impinges upon them from the fines (t, andthis heat, together with that which passes through the perforations c cof the plate F, dries out the moisture of the exhaust-steam dischargedby the pipe 0 into the chamber B, so that said steam passes out from thepipe D into the external atmosphere in the formof an invisible vapor.

The escape of dense White masses of steam directly into the open air, asis common in the use of steam-operated automobile vehicles, is a seriousobjection to their travel upon the streets of a city and is very liableto frighten horses, and thus to cause great damage. By the use of mysaid device this difficulty is avoided. p

When the fire is first started in order to make steam in the boiler A,the damper I should be open, so that the smoke will pass out through theupper end of the pipe D, and suitable means should be provided forsecuring the damper in such positiontemporarily, such as a hook orsimilar device; but when the steam has been made such fastening isloosened and the damper is thenceforth automatic. It is so Weighted thatit is nearly but not quite balanced by the counterpoise n upon the arm mthereof, and normally extends horizontally across the pipe D on the openbottom thereof a suction or tendency to a vacuum is produced in thelower portions of the chamber B below the plate F and tongue G, whichwill draw cold air up through the fire-receptacle and the fines a, thusreducing the temperature of the chamber B,as also the steam-pressure inthe boiler A. It is to obviate this tendency that the damper I ispivotally hung and weighted, as shown, for when such a condition isreached the suction downward in the pipe D at once draws the damper Idown, as indicated in dotted lines in Fig. 1, and air from withoutrushing inthrough the top of the pipe D immediately supplies the demand,thus protecting the fire fromexcessive draft, and as soon as the pressures are equalized the weight it brings the damper I automatically toits normal positionagain.

I claim as a novel and useful invention and desire to secure by LettersPatent- 1. The combination of a steam-boilerhavinghot-air fines throughit, a chamber above the boiler into which said fines open, a pipeenteringsaid chamber and adapted to convey exhaust-steam from areceptacle containing the same, a smoke-pipe and a pipe connecting saidchamber with the smoke-pipe, and a plate extending in a directionslightly inclined-from a horizontal line, through said chamber a shortdistance above the upper ends of said fines and located below saidsteam-pipe, substantially as specified.

2. The combination of a steam-boilerhaving hot-air fines through it, achamber above the boiler into which said fines open, a pipe enteringsaid chamber and adapted to convey exhaust-steam from a receptaclecontaining the same,a-smoke-pipe and a pipe connecting said chamber withthe smoke-pipe, and a plate having a series of perforations andextending in a direction slightly inclined from a horizontal linethrough said chamber a short distance above the upper ends of said finesand located below said steam-pipe, substantially as described.

3. The combination of a steam-boiler havinghot-air fines through it, achamber above the boiler into which said fines open, a pipe enteringsaid chamber and adapted'to convey exhaust-steam from a receptaclecontaining the same, a smoke-pipe and a pipe connecting said chamberwith the smoke-pipe, a plate having a series. of perforations arrangedin parallel rows, which plate extends in a direction slightly inclinedfrom a horizontal line through said chamber a short distance above theupper ends of said fines and located below said steam-pipe, and a seriesof angularlyinclined baffler-plates fastened to said plate and extendingover the rows of perforations, respectively, substantially as shown.

4. The combination of a steam-boiler having hot-air fines through it, achamber above the boiler into which said fines open, a pipe enteringsaid chamber and adapted to convey exhaust-steam from a receptaclecontaining the same, a smoke-stack open at both ends and a pipeconnecting said chamber with the smoke-pipe at a place intermediatebetweenthe ends of the smoke-pipe, a plate havinga series of.perforations. arranged in parallel rows, which plate extends in adirection slightly inclined from a horizontal line through said chambera short distance above the upper ends of said fines and located belowsaid steam-pipe, a series of angnlarly-inclined baifier-plates fastenedto saidplate and extending over the rows ofperforations, re? spectively,and acurved tongueextending from said plate through saidconnecting-pipeand down into the smoke-pipe,substantially as set forth.

5. The combination of a steam-boiler having hot-air fines through it, achamber above the boiler into which said fines open, a pipe enteringsaid chamber and adapted to convey exhaust-steam from a receptaclecontaining the same, a smoke-pipe open'at both ends and a. pipeconnecting said chamber and-smokepipe at a place intermediate betweenthe endsof the smoke-pipe, a plate havinga series of perforationsarranged in parallel rows, which plate extends in a direction slightlyinclined froma horizontal line through said chamber a short distanceabove the upper. ends of said fines and located below said steam-pipe, a
